| | This paper reports the bench scale experiment for the requirements of dry fermentation with agriculturol wastes.It is shown by the bench scale experiments that for dry fermentation the TS concentration should be 25-30%,the amount of inoculum more than 30% and the ratio of straw to pig manure by TS two or one to one.The pilot experiments indicated that the additions of inoculum and fresh pig manure in the period of fermentation when the biogas yield rate were lowering,were the key steps which played an impor... | | 本文报道了以农业废物为原料的干发酵工艺条件。干物质浓度(TS)以25-30%、接种量在30%以上、草粪比例(按TS计)以2—1∶1为宜。当产气率下降时,加入接种物和粪便,可延长产气率较高期的时间,提高总产气量和原料利用率。 | | 文摘来源 | | A comlex fertilizer of microelements and phosphorus sypsium was added into synthetic and manure composts for the cultivation of button mushroom. The fertilizer showed effects of increasing dry mycelial matter by 50.21—111.00%. fruit-bocies yield by 5.5—19.45% and 20.41—30.55% as compared with swo control treatments, respectly. After adding the fertilizer, the contents of protein, amino acids, vitamines, soluble sugars, minerals, etc. in fresh mushroom increased, whereas cellulose content decreased, this mad... | | 在无粪培养料和草粪培养料中加入复微石膏(MEPG),制作成MEPG培养料栽培蘑菇,可以促进菌丝增殖,比对照增加菌丝干物质50.21—111.00%;复微石膏无粪料比无粪合成料、复微石膏草粪料比草粪料的产量分别提高5.5—19.45%,20.41—30.55%;鲜菇中的蛋白质、氨基酸、维生素,可溶性糖和矿物质等营养成分含量都比对照高,唯独纤维素含量比对照低,这些都会使蘑菇更具有鲜嫩的品味。 | | 文摘来源 | | Nitrate and nitrite contents could be decreased for middle but increased for uppers in flue cured tobacco leaves by applying different organic manures.Comparison among different treatments indicated that it was the lowest for the nitrate and nitrogen content by applying fully fermented plant manure,followed by applying tung oil cake,and the highest by applying chicken droppings with tung oil cake. | | 施用不同的有机肥 ,对降低烤烟中部叶片硝态氮含量有一定作用 ,但上部叶的硝态氮含量有所提高。比较而言 ,以施用腐熟草粪的处理烟叶硝态氮含量最低 ,其次是施用桐油枯 ,烟叶硝态氮含量最高的处理是施用鸡粪 +桐油枯。 | | 文摘来源 | |   |
